FunFam 3021: Tubulin gamma chain

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Nucleoside-triphosphate phosphatase. [EC: 3.6.1.15]
NTP + H(2)O = NDP + phosphate.
  • The enzyme is found in eukaryotes and thermophilic bacteria, but appears to be absent from mesophilic bacteria.
  • Also hydrolyzes nucleoside diphosphates, thiamine diphosphate and FAD.
  • The enzyme from the plant Pisum sativum (garden pea) is regulated by calmodulin.
 2 A0A170XZR8 A0A170XZR8
Glycerophosphodiester phosphodiesterase. [EC: 3.1.4.46]
A glycerophosphodiester + H(2)O = an alcohol + sn-glycerol 3-phosphate.
  • Broad specificity for glycerophosphodiesters; glycerophosphocholine, glycerophosphoethanolamine, glycerophosphoglycerol and bis(glycerophospho)-glycerol are hydrolyzed.
 2 A0A0L1HGK8 A0A0L1HGK8
Dihydrolipoyl dehydrogenase. [EC: 1.8.1.4]
Protein N(6)-(dihydrolipoyl)lysine + NAD(+) = protein N(6)-(lipoyl)lysine + NADH.
  • A component of the multienzyme 2-oxo-acid dehydrogenase complexes.
  • In the pyruvate dehydrogenase complex, it binds to the core of EC 2.3.1.12 and catalyzes oxidation of its dihydrolipoyl groups.
  • It plays a similar role in the oxoglutarate and 3-methyl-2- oxobutanoate dehydrogenase complexes.
  • Another substrate is the dihydrolipoyl group in the H-protein of the glycine-cleavage system, in which it acts, together with EC 1.4.4.2 and EC 2.1.2.10 to break down glycine.
  • It can also use free dihydrolipoate, dihydrolipoamide or dihydrolipoyllysine as substrate.
  • Was first shown to catalyze the oxidation of NADH by methylene blue; this activity was called diaphorase.
  • The glycine cleavage system is composed of four components that only loosely associate: the P protein (EC 1.4.4.2), the T protein (EC 2.1.2.10), the L protein (EC 1.8.1.4) and the lipoyl-bearing H protein.
  • Formerly EC 1.6.4.3.
